NLT or DLT Panels Connect with Single Surface Spline

Adjacent floor panels are butted together. A plywood spline is fastened to both panels using partially-threaded screws or nails.

Purpose: Transfer of in-plane shear along the panel-to-panel joint.

Design Notes

The capacity of the connection is controlled by the shear capacity of dowel-type fasteners.

  • Common for NLT and DLT panels.
  • Panels are manufactured with a layer of sheathing held back from the panel
    edges to accommodate splines.
  • Where using nails, consider specifying nail gun nails instead of common wire
    nails for constructability, or collated screws instead of individual screws.
  • Where screws are used instead of nails, cost increases and constructability
    is moderate.
  • Coordinate spline width and thickness with panel supplier.
  • For guidance on fasteners within panels, see the Nail-Laminated Timber U.S. Design & Construction Guide.
